LIQUID-PROJECTING APPARATUS.

Speoieation of Letters Patent.

Patented Apr. 2d, 191i 7 Application filed April 29, 1916. Serial No.`94l,323.

America, residing at Brooklyn, in the county I of Kings and State of New York, have invented certain new and useful Improvements in. Liquid-Projecting Apparatus, of which the following is a specification.

My invention relates to a liquid pro]ect instrument, of the type generally termed liquid pistol, or squirt gun.

The principal objecty of 4the invention is to provide a device of this kind which shall be capable of use after the manner of a repeating gun, that is one in which quantities of liquid may be ejected at intervals, such? quantities being taken from a reservoir forming part of the device.

A further object of the invention is to vprovide an exceedingly simple construction in which I dispense with valves to control the emission of liquid, and provide in lieu thereof a special form of trigger operated cell which governs liquid ejection.

Another object of the invention is to eliminate all valve mechanism over the liquid reservoir, to admit air in compensation for the liquid withdrawn, and to substitute for suc valve mechanism a special type of plug through which air mayenter the reservoir.

Other vobjects of the invention, its advantages and detail construction, will be described in the following specification referaccompanying drawing, in whichy Figure 1 is avertical sectional view of the device in a position of rest;

Fig. 2 is a similar view thereof in the position of liquid ejection;

Fig. 3 is a vertical sectional view of a portion of the barrel and appurtenant parts on anv enlarged scale; and

Fig. 4 is a fragmentary sectional view of Referring to the drawing by reference characters, 10 denotes the stock or handle which is hollow so as to provide the liquid The handle may be ofi-any desired shape, although the substantially rectangular form shown in the drawing is or lhandle and the best suited for the purpose of supplying adequate space for the reception of a suicient amount of liquid 12.

In suitable relation to the stock 10 is the barrel 13 which is preferably formed as an integral part of the stock, the rear wall 13a of the barrel being positioned approximately over the median vertical line of the stock 10. rThe barrel 13 is provided with an elongated slot 1&1, in its lower portion, to

permit of reciprocatio of the trigger 15.

The trigger 15 is rigid with a cell 16,

slidable in the barrel 13. The rear wall lof the cell is orificed as at'17, to allow for the passage of a stationary piston therethrough,

and its front wall is provided with a very considerably constricted ejection nozzle 18.

The cell is normally pressed toward the front of the barrel by a coiled spring 16a.

Secured to the rear wall 13a of the barrel ris a curved tube 19 which extends into the stock 10 and terminates a short distance above the base'lOa of the stock. Near its 75 upper curved end, the tube 19 has a collar 20 which abuts one face of the wall 13a, adjacent collar 20, the tube 19 projects beyond the wall 13a and has its projecting end threaded to receive the correspondingly interiorly threaded end of a hollow piston 21. The end of the piston 21 which engages the tube 19 is also exteriorly threaded to receive a nut 22 whereby thepiston 21 and tube 19 are firmly held together in position on the wall 13a. interposed between the nut 22 and the wall 13@L is a washer 23 of any suitable material.

The opposite end of the hollow stationary piston 2l is exteriorly threaded and carries 90 thereon oppositely cupped washers 24 and 25 which are held in position by disks or plates 26 and 27 engaging respectively the washers 24 and 25. The cupped faces of these was/hers make frictional contact with the interior surface of the cell 16.

Traversing the hollow piston 21, intermediate its ends, is a pin 28 to which is secured one end of a spiral spring 29, the other end of which engages the-tailof a valve 30.

This valve isv substantially mushroom shaped and the periphery of its head is fairly sharp and engages the outer face of the disk 27. rlhis construction of valve 36 character, impregnated with oil.

is adopted so as to minimize the danger of particles lodging between the valve 30 and the disk'27 and impeding the operation of the device.

The upper wall of the stock is provided with a suitable orifice to receive a plug 31. This plu has a central bore into which is placed fi rous material 32 of any suitable The top of the plug is covered by a disk or plate 33 having therein a small opening 34. The construction of the plug is such that when liquid -is withdrawn from the reservoir 11, air to replace such liquid is sucked through the opening 34, the central bore in the plug, and into the reservoir 11. Owing to the fact that the fibrous material 32 is impregnated with oil, such fibrous material will exert no capillary attraction on the liquid 12 and will not draw the same out of the reservoir 11. l

The device operates substantially in the following manner: First remove the -plug 31, ll the reservoir about the level shown in Fig. 1, and then replace the plug 31. Before any operation of the device the parts are in the position shown in Fig. 1 and the cell 30 'is iilled with air. Upon retraction of the trigger 15'the cell 16, which is freely movable in relation to the fixed piston 21, is retracted within the barrel and the air contained in such cell is expelled through the restricted nozzle 18. During the retraction of the cell 16 the spring 16a has been compressed. When the trigger 15 is released the spring 16a expands and projects the cell in the barrel. As a result of this forward movement of the cell the internal capacity of the .latter is increased tending to the development of subatmospheric pressure therein. This subatmospheric pressure results in unseating the valve 30 and drawing or sucking water from the reservoir 11 through the tube 19, stationary piston 21 and intothe cell 16. The nozzle 18 is of such a restricted character as to counteract any .tendency to drawl a substantial quantity of air into the cell 16 to break the vacuum retraction of the cell 16 by means of the trigger 15 `the water in the cell will be exelled in a line stream through the nozzle 18 and the front opening 35 in the barrel.

This operation is repeated as frequently as the trigger is actuated and until the reservoir 11 has been emptied of water.

It is evident that' the pistol may 'vcharged, repeated as often as there is 'reservoir 11 to compensatefor the liquid in the reservoir 11.

During each discharge of the pistol air will flow through the hollow plug 32 into the ,of liquid withdrawn from the latter.

The cupped washers 24 and 25 prevent any liquid which enters the forward part of rel, a piston in said barrel,

11 with liquid 12 up to therein. Then upon a secondv be disquantity the cell 16 from finding its way to the rear part of-such cell. l

The front end of the barrel is provided with the inturned end or flange 13@L to limit the forward movement of the cell 16, under the action of the expanding compressed air.
